Well, Medicare is underfunded to the tune of $38T. If all of Google and Apple was liquified at current market cap and put towards funding that liability, it would be underfunded by at little more than $37T. Retroactively cancelling the Iraq and Afghanistan wars would give you cash to knock the number down to $36T.
Of course people benefiting from Medicare benefits from Medicare, but "championing" Medicare benefits only politicians, because they know better than anyone else that it's going to go away, soon, but they'll happily lie about it in order to get reelected while they wait for it to happen.
